NFL Media Insider Ian Rapoport reported that Gary Kubiak, as expected, returned to the team's facility Monday, according to a Texans source.

Kubiak isn't expected to work a full day after suffering a mini-stroke on Nov. 3, but Rapoport noted Sunday that the longtime coach is anxious to get back to business amid whispers that Houston's front office is "a bit frustrated" with Kubiak and his assistants.

That frustration channels from the coaching staff holding too much sway over the draft process and, according to Rapoport, keeping the team's stars on the field too long. A string of defensive collapses have been pinned on a D-line that wears down late, something the Texans were guilty of against the Colts after interim coach Wade Phillips stepped in for Kubiak two Sundays ago.
